“Bought a 2006 5.9 Cummins knowing that it was missing but had to have her. Took it to the shop and they said #3 was reading at 1.6 and needed to be replaced. My 16 year old son told me about a stiction remover he saw on Truck U. Did my research and found your product. I am 350 miles into the oil change with adding the Hot Shot Stiction Eliminator and also the Diesel Extreme to my fuel and my baby is already running 80% better! Can’t wait to see what your product continues to do for her!”
“I was searching around on youtube for similar hard cold start problems like I was having with my 06 F350. Some how I stumbled on a video of the Hot Shot’s Secret . I watched a few video’s, then I found one that explained about stiction and had a cut away of an injector with oil built up inside of it. Then I got to thinkin’…..maybe I’m treating the wrong side of the injector? A couple video’s later, I went on the hot shot’s website to locate it. Found it at Travel America truck plaza in Pembroke N.Y., bought some and went back home to change the oil in my truck. 300 miles later I’m already noticing a difference. I’m going to take another video of me starting my truck in the cold temps and post to youtube. (before and after video’s. I wish I would of took that video this morning when it was -4 degrees.) Long story short………….I’m a believer.”
In recent years, the term “stiction” has joined the conversation between diesel mechanics and drivers. But what is stiction, exactly?
This simple demonstration will help you visualize stiction. Pour a small amount of water on a counter-top. Now slide a paper towel over the spill. Feel the difference in the amount of drag after the towel absorbs the water. That drag is stiction.
Imagine the inside your diesel’s injector. A thimble full of engine oil has the high pressure job of driving the intensifier piston under extreme heat. Over time, that small amount of engine oil breaks down and leaves a gummy residue on the internal parts. As those parts move, they experience a drag (like the wet paper towel). The sticky, gummy residue of burnt oil on moving engine parts causes a dragging friction. We call that stiction.
Drivers sometimes choose to use lubricants to resolve stiction. This creates a temporary improvement as lubricants can relieve the dragging effect for only a short time. Lubricants are not designed to remove the sticky burnt oil residue which is the cause of stiction. A short time after a lubricant has been added, the stiction symptoms return. Treating stiction with a lubricant is like spraying cooking oil on a dirty frying pan. It only masks the problem. Actually, stiction’s negative impact to your diesel’s performance never left as it was simply masked by the lubricant.
Stiction can occur on your diesel’s injectors, o-rings, springs, piston and the turbocharger. The most obvious symptom of stiction is a diagnosis of a failed injector. Common symptoms of stiction occur well before your mechanic runs the diagnostics on your engine. If you are experiencing slow starts or bucking and chugging, especially on cool mornings, stiction could be building up. If your diesel hesitates to accelerate or has been losing power, then you could be experiencing stiction. A steady and consistent drop in your MPG can also be an indicator of a stiction problem. To eliminate these symptoms, choose an additive specifically designed to remove stiction.
It’s one of those experiences that diesel owners prefer to avoid. Having to choose between an expensive repair or operating at impaired efficiency. A diagnosis of a “failed” injector can cost thousands of dollars in replacement costs. However, a closer look at the problem reveals an interesting insight.
Since the introduction of the 7.3 L Power Stroke in 1994, injectors have been relying on oil pressure to fire the piston via the HEUI fuel system. International pioneered the idea of electronically controlled diesel engines in pickups, which became commonplace on GM and Cummins diesels. Inside the injector, barely a thimble full of oil has the job of lubricating the piston, springs and o-rings. This oil is exposed to temperatures much higher than reported on your engine temp gauge. With enough time and heat, the oil breaks down and leaves a gummy residue on the inside of the injector. This “gumminess” can cause a slight hesitation in the piston or spring release which can cause a diagnosis computer to trigger a “failed injector” code. This gummy, sticky, friction is called stiction.
Frequently mechanics recommend replacing the injectors after the failure code is triggered. This is where the myth comes into play. While it is true that a replacement will solve the problem of an injector not performing correctly due to stiction, it is often unnecessary. The logic behind this replacement recommendation would be similar to replacing a leaky tire instead of plugging it, especially when there are plenty more miles to roll on that tire. Why replace an injector that is designed to go 1,000,000 miles? The elements of an injector are well crafted and can perform for the life of the engine. It is the stiction that is causing the failure, not the malfunctioning of the injector elements. Thus the “failed” injector myth.
While many drivers choose fuel additives to improve performance, the stiction that is causing an injector failure requires an oil additive. This is often counter-intuitive to diesel owners who consider the injector as part of the fuel system, not the oil system. Injectors require both systems to perform. A problem specific, high concentrate oil additive can remove the stiction and restore it to its original factory performance.
Common symptoms of stiction occur well before your mechanic runs the diagnostics on your engine. If you are experiencing slow starts or bucking and chugging, especially on cold mornings, stiction could be building up. If your diesel hesitates to accelerate or has been losing power, then you could be experiencing stiction. A steady and consistent drop in your MPG can also be an indicator of a stiction problem.
Chris Gabrelcik is certified with STLE as a CLS and OMA. He personally developed and tested a product designed to remove stiction called Hot Shot’s Secret Stiction Eliminator.
Hot Shot’s Secret Diesel Extreme will improve cetane in the fuel giving it a smoother, less erratic pressure buildup in the combustion chamber during the ignition delay period, which occurs between injection and ignition. Controlling this pressure buildup eliminates the potential damage to piston rings and rod bearings. Power and fuel economy is increased as fuel burns more evenly and cleanly. Misfiring is controlled. When ignition improves, emissions are reduced and noise levels are lowered. Control of the pressure buildup allows more complete burning of the refractive molecules in the fuel, which steal power and produce deposits and wear. Cetane improvement gives quicker starts and faster warm-up at cold temperatures. Hot Shot’s Secret Diesel Extreme will lower the minimum starting temperature of a diesel engine approximately 5°F.
We have been testing Hot Shot’s Secret Stiction Eliminator since 2004 and have found it to be 90% effective. Trucks having problems were hooked up to a diagnostic computer and tested. Computer analysis showed anywhere from 1 to 6 injectors needing replacement. A treatment of Hot Shot’s Secret Stiction Eliminator was added to the engine oil. The trucks were run only 100 miles and then the computer analysis was repeated. 86% of the time, the analysis showed all the injectors were back online. The owners noticed more power and a smoother running truck. The other 10% of the trucks showed improvement also, but not a complete cure. Most of the time, the diagnostic analysis showed that 4 injectors needed replacement before treatment. After Hot Shot Secret Stiction Eliminator was added to the engine, the analysis consistently showed only 1 injector needing replacement.
“I was pulling my 5th wheel and boat up a mountain pass and was losing power at 3000 rpms in every gear. Took it to a Diesel repair shop and after testing on a dyno machine I was told two injectors and my injector pump where going out. I saw Hot Shot’s Secret shown on Trucks TV. I decided to give it a try before spending $1800 on parts alone. I replaced two quarts of oil with Stiction Eliminator during last oil change. Six hundred miles later had truck put back on the dyno machine and passed with full power! This stuff works so Thanks Hot Shot’s Secret Company!”
